SPECIFICATION forming part-of Letters Patent No.` 530,602, dated December 11, 1894. Appncaion fina May 31,1894. stan 110,513,067. (No man To @ZZ whom it may concern.`

citizen of the United States, residing at Rockford, in the county of `Winnebago and State 5 of Illinois, have invented certain new and useful Improvements in Chmn-Covers, of which the following is a specification.,

The object of this invention is to construct a churn closure in which the center portion 1o is constructed of enameled metal, held in place bya metallic casing.

The further object of this invention is to hold a glass over an opening in the cover by the casing, and the further object of this in- :5 vention is to form a detachablemonnection between the center portion Iof the cover and the casing. e v l In the accompanying drawings, Figure 1, is an isometrical representation of the cover zo showing its upper surface. Fig. 2, is an isometrical representation of the under faceof the casing. Fig. 3, is an isometrical representation of the upper surface of the center portion. Fig. et, is a vertical bsection through the 2 5 complete cover. Fig. 5, is an enlargedsection of a portion of the center showing the opening for the glass. p

In the construction of covers forchurns the center portion is usuallylnade from wood,

3o beveled by a metallic rim, and in such construction the wooden portion would by the action of moisture and heat soon crack and split, and these crevices in the wood form ret ceptacles for the lodgment of particles of 3 5 cream, which soon become rancid, and soon render the cover useless, and it is these disadvantagesthat I seek to overcome by my improved construction of cover. A

The center portion l, ot` the `cover is con- 4o structed from sheet metal having a rim 2, at

" its outer edge and from which extends a ange 3, lying in the same plane as the main portion. To the center of the center portion and to its upper face is riveted a catch composed 4 5 of ears 4, vertical edges 5, and a horizontal top 6, having a portion 7, cut away. To one 5o this hook is a hole, or opening 10, and holes `from the center of the brace rises a boss `16,

having a square central opening 17. The under face of the central portion of the brace is provided with a recess 18, to receive the catch y secured `to the upper faceof the center, and 65 has a portion 19, cut away as shown at Fig. 1.

3A circular recess 20, is formed in the enlarged `portion of the brace and in the bottom of this recess is formed a square recess 21, which is provided with a circular opening 22, of a 7o diameter equal to the circular opening 10, in the enameled center portion. A recess 23, is also formed in the under face of the brace which receives the hook 8. Screw threaded holes 24, are formed in the ring 18, at the 7 5 point of connection of the brace.

In securing the parts of the cover together a suitable packing is placed around the opening 10, in the enameled center, and within `the square recess 21, in the under face of the 8o brace is placed a square of glass 25, anda bolt 26, is placed within the slotted end of the hook 8. The outer casing is then placed over the enameled center, the bolt passing upward through the. perforated boss 27, receiv- S 5 ing atnut on its upper end lirmly clamping the brace and enameled center together at this point. In center in the casing in its connection with the center, the catch will enter the recess 18, in the under face of the brace, 9o and the head of the bolt 28, is passed through the opening 19, in the upper face of the brace and central boss 16, the square portion of the bolt near its head entering the square opening in the boss. A nut 29, placed uponthe bolt 9 5` and turned down against the upper surface of the boss will form a connection between the catch and brace, the opening in the catch permitting` the entrance of the shank portion of the bolt. Screws 30, are passed through roo holes 11, in the flange into the threaded holes 24 in the casing forming a connection between the center and casing.

In placing the casing in position over the enameled center the glass 25, will be firmly embedded in the packing laid around the cir-` cular opening 10, in the center.

Between the pepending rim 14, of the casing and the rim 2, of the enameled center when the parts are joined as herein described will be formed an annular recess, within which is seated a suitable packing ring 3l, and is held in place by its pressure against the rims which form a seat for the end of the churn or other device for forming awater tight joint between the cover and churn body. The depression 32, formed in the under face of the brace receives the heads of the rivets, securing the catch and hook to the enameled center.

To the screw threaded end of the bolt 28, may be attached the devices acting in conjunction with other devices having a connection with the churn body for holding the cover in its connection with the churn body, and may be any of the various devices employed for that purpose.

In the employment ot' the enameled center it is necessary that all independent parts having a connectionltherewith should-be riveted thereto and be composed of metal which will expand and contract uniformly with the cen-` ter in order to avoid cracking ot' theenamel,

and after it has been enameled it will not stand very rough usage. By this construction the glass will be held firmly in position, and the opening will be perfectly sealed, preventing leaking at this point.

I claim as my invention- 1. A cover for a churn consisting of a center, a metallic casing surrounding the center, having abrace integral therewith and overlying the center, a projection secured to the upper face of the center and means yslidably connecting the projection with the brace.

2. A cover for a churn consisting of a center, a metallic casing surrounding the center having a brace integral therewith and overlying the center, a catch secured to the upper'face of the center, anda bolt slidably connecting the catch and brace.

3. A cover for a churn consisting of a center, a metallic casing surrounding the center having a brace integral therewith and overlying the center, the brace having a recess in its under face, a catch secured to the upper face of the center and located in the recess of the brace and means connecting the catch and brace.

4. A cover for a churn consisting of a center, a metallic casing surrounding the center having a brace integral therewith and overlying the center, the brace having a recess in its under face, a catch secured to the upper face of the center and located in the recess of the brace, a bolt engaging the catch, a nut located on the bolt clamping the catch to the brace.

5. A cover for a churn, consisting of a center, a casing having a brace, a catch secured tothe center, a recess in the under face of the brace receiving the catch, the upper surface ot' the brace supporting a boss having a. portion of one face cut aw'ay, a bolt connectingthe center and brace, the head of the bolt adapted to pass under the-catch through the cut away portion.

6. A cover for a churn, consisting of a center, a metallic casing surrounding the center having aprojection extending inward therefrom andintegral therewith, a glass'located between the projection and center, a hook secured to the upper face of the center and means connecting the hook and projection.

7. A cover for a churn consistingof a center, a metallic casing surrounding the center having a projection extending inward therefrom andintegral therewith, a glass located between t-he projection and center-','ahook secured to the upper face ofthe center and means connecting the hook and projection.
